| supported channels = 2 * xlnx,num-channels |
| |
| Example: |
| |
| i2s_receiver@a0080000 { |
| compatible = "xlnx,i2s-receiver-1.0"; |
| reg = <0x0 0xa0080000 0x0 0x10000>; |
| xlnx,dwidth = <0x18>; |
| xlnx,num-channels = <1>; |
| }; |
| i2s_transmitter@a0090000 { |
| compatible = "xlnx,i2s-transmitter-1.0"; |
| reg = <0x0 0xa0090000 0x0 0x10000>; |
| xlnx,dwidth = <0x18>; |
| xlnx,num-channels = <1>; |
